CAN-CAPPING MACHINE.

$PECIFIGATION forming part of Letters Patent No. 672,749, dated April 23, 1901. Application filed May 12, 1900. Serial No. 16,414. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES L. BAENDER, a citizen of the United States, residing at Pittsburg in the county of Allegheny and State of Pennsylvania, have invented new and usefulImprovements in Can-Capping Machines, of which the following is a specification.

This invention relates to machines for soldering the caps or covers on tin cans; and its primary object is to provide improved mechanism for delivering a predetermined amount of solder for each soldering operation and also to make such mechanism adjustable to deliver greater or less amounts, as required.

Further objects are to provide a combined melting-pot and soldering-iron of improved form and to provide improved actuating mechanism.

The invention consists in the novel features of construction and in the combination and arrangement of parts hereinafter fully described and claimed, and illustrated by the accompanying drawings, in which- Figure 1 is a vertical sectional view of the operative part of the machine, showing the solder delivering or ejecting plunger in lowered position, as when delivering the solder to the iron. Fig. 2 is a similar view of the lower portion of the machine, the plunger being shown raised in solid lines to receive the solder and in dotted lines in extreme lowered position for cleaning the plunger. Figs. 3 and 4 are detail views of a form of actuating mechanism. Fig. 5 is a similar View of the burner which encircles the melting'pot.

Referring to the drawings, 2 indicates the solder-meltin g pot, open at the top and formed with a central annular opening in the bottom.

Depending from the bottom of the pot is the circular soldering-iron 3, here shown downwardly tapering in cross-section and integral with the pot, though not necessarily so. EX- tending axially through the pot is rod 4, threaded at the lower end to receive the threaded plunger-sections 5 and 6, and also lock-nuts 7 and 8. Plunger-section 5 is cored out at 5, and section 6 is reduced at 6 to fit thereinto, so that the annular space or pocket 9 between said sections, and in the outer wall of the plunger, may be enlarged or contracted to receive a greater or less amount of solder from the pot when in raised position (shown in solid lines in Fig. 2) and deliver it to the inner tinned wall or face 3' of iron 3. As the plunger snugly fits the bottom opening in the pot, no solder can escape from the latter excepting in pocket 9, so that each charge is accurately gaged and may be varied in amount by raising or lowering plunger-section 5 on rod 4. The annular edge of iron 3 fits the solder-groove of can 10, and the latter or the iron is rotated by suitable mechanism. (Not shown.) Wall or face 3 of the iron being tinned, the molten solder flows freely thereover, and the discharge thereon from annular pocket 9 being equal at all points the work is made uniform.

Plunger-section 5 is formed'at its upper end with flange 11, which when the plunger is lowered into position (shown in dotted lines in Fig. 2) sustains the latter with the pot sealed against the discharge of solder, and with the plunger thus projected it and pocket 9 may be effectually cleaned.

12 is a substantially circular burner sustained by hangers 13 exterior of the pot and iron and in such position as to maintain the pot and iron at proper temperature and with the solder in a molten state, the latter being supplied to the pot in lumps or in any other preferred form. Burner 12 is closed at one end and outwardly turned at 12' at the other end to receive a gas supply hose. (Not shown.) 14 is a finger projected into the iron through slot 15 in the latter for engaging the can-top 10 and holding it in place during the soldering operation.

In operation either the can or the soldering mechanism may be moved vertically to bring said elements together for the soldering operation. I here show mechanism for vertically moving the soldering-machine, and the same consists of rods 16, rigid with frame 17, raised from the top of pot 2, said rods working through fixed guides 18, projecting laterally from support 19. Vertically adjustable on rods 16 is head 20, to which operating-lever 21 is connected by link 22, the lever being fulcrumed to support 19. Ad-

justable on the upperportion of plunger-rod 4 is head23, connected by links 24: to lever 25,

the latterbeing fulc rumed to support 19 beneath lever 2l andadjustably secured to the latter by link 26, lever 25 being slotted at 25 to provide for said adjustment, whereby the relative vertical movements of the plunger and pot may be varied. With the mechanism here shown the soldering-machine may be raised or lowered on the levers, andthe fixed guides will always hold it in vertical line. However, I do not restrict myself to the actuating mechanism here shown, as the pot and plunger may be operated in a variety of ways, or the plunger alone may be caused to operate, the pot remaining fixed, with the can movable with relation thereto.

In using the term pot in connectien with the solder-container Ido not thereby restrict myself to a melting-pot. Said element may be styled a reservoir or container, in which the solder is preferably, though not necessarily, reduced to molten state.

Having thus fullydescribed myinvention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a soldering-machine, the combination of a solder-container, an iron, mechanism for delivering predetermined quantities ofsolder from the container to the iron, and means for adjusting said delivering mechanism, whereby said quantities of solder may be varied, substantially as shown and described.

2. In a soldering-machine, the combination ofa pot, a soldering-iron, mechanism adapted to deliver a predetermined quantity of solder to the iron at each operation of the machine, and means for varying the quantity of solder carried by said delivering mechanism, sub stantially as shown and described.
